;To all whom it may concern: Y

Be it known that I, Anromn Sonny, of Lyon, France, a citizen of theFrench Republic, have invented certain new and'useful Improvements inLubricatingrcups, of whichthe following is a specification.

e of the cap is serrated and the said cap can be rocked in any directionin order to expose one or other of the openings formed by the serrationsin its edge and through which is introduced the nozzle of the oil canfor fill-f ing the lubricator. The cap is restored to its medialposition by means of a laterally flexible spring which is so arrangedthat one of its ends is axially secured internally to the lubricator andthe other end is similarly cap in such manner that the spring constantlytends to restore the cap to its normal position and tends to keep it insaid position in order to insure "a dust-tight closure.

The annexed drawing shows an example of construction of the invention.

Figure 1 is a vertical section of the oil cup, the cap of which isclosed.

Fig. 2 is a plan view of- Fig. 1.

Fig. 3 is a similar section, the cap being open and Fig. 4 is anelevation of the lubricator arranged horizontally, the cap being open.

The lubricator is composed of a body a having .a cylindrical outersurface comprising a hexagonal surface either at b or at c, as

shown in Fig. 4, this hexagonal surface serving for putting in place orremoving the lubricator. The inside of the body a is conic at its baseand spherical at its top at d. i

The cap or lid 6 is a portion of a'hollow sphere larger than ahemisphere on theedge of which are provided semi-circular andequidistant notches h. It is provided with a button 9 projectingexternally and prolonged inside the sphere by a pin of which the lengthis so determined that it does not reach the central point of the sphere.

The otherend of said spring engages on the pin of the button g V and 1s thusattached to the cap e,"as shown in Figs. 1 and 2.

The length of said spring is so calculated that it is slightlycompressed when the cap 6 is placed in the body a so that the edge ofthe cap presses against the spherical part d.

In ,mounting the parts, the edge 8 of the part b of the body a isafterward turned in against the outer surface of the sphere, while stillleaving the necessary play for allowing the rotation of said sphere inits socket, from which it can no longer beremoved after the aforesaidedge has been turned inward.

The slight compression of the spring f is suflicient to constantly pushthe cap against the edge of the socket (Z without preventing the freerotation of said cap by the operators fingers which grasp the button 9on the. surface of the cap. I

This cap can be rotated horizontally on its own axis as the spring isnot secured to the pin of the button 9 and it can also be tilted in alldirections while bending the spring 7 as shown in Fig. 3. Owing to saidsimultaneous or successive rotation and tiltof the lid there is obtainedwithout trouble a lubricating hole whatever the position of the body a,as one or other of the notches h is brought forward and through whichtheoil can be introduced into the lubricator by passing through saidorifice.

The oil cup can be arranged horizontally as'represented in Fig. 41 or inany inclined position between the horizontal and the vertical.

leased it immediately returns to its normal position (Fig. 1) under theaction of the spring f. The closure is thereforeautomatic anddust-tight, and there is no fear of leakage of oil when the lubricatoris'in an inclined or horizontal position.

The lubricator cup can be constructed in When the cap hasbeen tilted andthen re- I i What I claim as my invention and desire to secure byLetters Patent of the United States is Y 1. A cup comprising a bodyhaving a bore and a chamber having an internally spherical mouth incontinuation of. said bore, a hollow cap in the form of a portion of asphere larger than a hemisphere fitting in said mouth and a lateralspring one end of whichis axially fixed in said body and the other endaxially fixed in said cap and allowing said cap to be tilted to allowoil to' be introduced into said chamber, the said spring automaticallyretarding said cap when released to the closed position.-

thereby.

A lubricating comprising a body having a bore and a chamber having aninternally spherical mouth in continuation of said bore, a'hollow cap inthe form of a portion of a sphere larger than a hemisphere fitting insaid mouth, a knob on the exterior of said cap, a pin forming, anextension of said knob extending-into said cap, and a laterally flexiblehelical spring, the one end of which surrounds said pin and is axiallyheld thereby, and the other end fits tightly into said bore and isaxially held In witness whereof I have signed this specification in thepresence of two wit- DGSSGS. p
